Overview

Note: Land-Form PROFILE has been withdrawn by Ordnance Survey and is no longer updated. Land-Form PROFILE has been superseded by OS Terrain™ 5.

Land-Form PROFILE provides detailed height data surveyed at a scale of 1:10,000. The dataset is available as Contours and as a Digitial Terain Model (DTM).

Contours are at 5 metre vertical intervals and 10 metre vertical intervals in some mountain and moorland areas. The dataset also includes air heights, spot heights, and high and low water marks. Digital contour accuracy values are typically better than half the contour interval, that is ±2.5 metres for areas with 5 metre vertical intervals and ±5 metres for areas with 10 metre vertical intervals.
